250+ TOP MCQs on Size Reduction Grinding Principles

Clarification: Determination of energy required in size reduction is generally done using Kick’s law or Rittinger’s law. The Rittinger’s law is stated as the energy required for reduction in particle size of a solid is directly proportional to the increase in surface area. The kick’s law is defined as the amount of energy required to
